Geochemical Modeling - Idaho National Laboratory

Geochemical models for the eastern Snake River Plain aquifer system are being used to better understand the flow of groundwater beneath the INL and, ultimately, to better understand the fate and transport of radiochemical and chemical constituents. As water moves through the ground, it picks up chemicals from the gases and rocks it comes in contact with.

Developing Geological Framework - Idaho National Laboratory

As basaltic lava cools and hardens, the inclination, declination, and polarity of the Earth’s ambient magnetic field is recorded in the magnetic minerals of the rock. The recorded magnetic values are largely preserved and can be deciphered by paleomagnetic analysis.

Drilling and Coring - Idaho National Laboratory

We drill and maintain wells around the INL to monitor and sample groundwater, obtain basalt and sediment cores for study and analysis, and study the physical properties of the subsurface (geophysical logging).

This information helps us to improve the scientific understanding of the eastern Snake River Plain and its aquifer. In particular, we are examining the subsidence of the plain and...

Video Logging - Idaho National Laboratory

Drillers use the vertical and horizontal views captured by our downhole video camera to examine borehole integrity before placing water well casing, well screens, and submersible pumps. Hydrologists and geologists use the images to verify geophysical data such as: changes in rock type, small-scale geologic structures, rock fractures, and groundwater movement.

Geophysical Logging - Idaho National Laboratory

Our scientists collect geophysical data from wells to understand the character of rocks and fluids below the surface. Geophysical data for a well are recorded, interpreted, and then disseminated as a geophysical log. Engineers and well drillers use geophysical logs to make well construction decisions such as design for well casing, well screen, and pump placement. Hydrologists, geologists and...

Water Archive Library - Idaho National Laboratory

Since 1966, we have archived over 6000 samples of about 500 mL each of "raw" (unfiltered and unpreserved) water from groundwater and surface-water quality sites collected during our monitoring activities. Through the years, we've kept the water samples in a secure room and tracked which samples researchers have requested and analyzed for various projects.
